Article Synopsis
- The study investigates how the age-related microRNA miR156 influences the development of extrafloral nectaries (EFNs) in two species of passion flower.
- Results show that manipulation of miR156 affects both leaf maturation and EFN formation, with overexpression leading to smaller and fewer EFNs, while reduced activity results in larger EFNs in one species.
- This research highlights a connection between miR156 activity, nectar sugar profiles, and the ecological interactions between EFNs and ants, underscoring the role of the miR156/SPL module in regulating these traits based on leaf age.
Article Synopsis
- The research team has focused on the natural dye-producing plant, annatto, gaining insights into its gene expression and regeneration processes.
- They have also explored gene editing techniques to improve bixin biosynthesis and breeding practices for this important species.
- The text outlines a detailed protocol for somatic embryogenesis and an optimized method for transforming annatto using Agrobacterium tumefaciens.
An efficient procedure for in vitro propagation of Herreria salsaparrilha Martius was established from single-node explants (fourth and fifth nodes from apex to the base) derived from donor plants maintained under shading-house conditions. After surface sterilization, explants are inoculated in test tubes containing 15 mL of Murashige and Skoog (MS) medium without growth regulators. Cultures are maintained under 35 μmol m s irradiance, a 16/8-h light/dark light regime, at 26 ± 2 °C.
